AT&T has the iPhone, consumers will flock to it- data speeds, the network doesn't mean anything... oh wait... they really can't use that plan now, huh? Wait, what's plan b now?
I had the worst experience with AT&T in terms of reliability. In terms of speed, yes, AT&T is faster. Blows Verizon away.
On AT&T, I could load up 3 web pages. The first one will load up in 2 seconds, then it will take 10 minutes to load up the other two webpages with full signal strength and a frozen blue progress bar. Meanwhile my boss who is trying to reach me has just left his 2nd voicemail with an increasingly angry tone and I won't get the voicemails until 30 minutes later.
On Verizon, with the same 3 web pages, the first one will take 10 seconds to load, then another 10 seconds for each additional webpage. And people can contact me... OMG!
So it's the tortoise vs. the hare and the tortoise wins.
